Split recordings, lectures, podcasts, interviews, voice notes, or long music files into smaller audio clips without uploading the source.
Interval and selected-range splitting
Use Every N seconds to divide the whole track into regular segments. This is useful for long recordings, transcription batches, and upload limits; multiple clips download together. Use Selected range when you need one exact excerpt.
By silence
Cuts are placed in the middle of qualifying silent gaps. Audio is retained, including pauses. Review the proposed cuts before exporting.
Time and output options
Start and end positions accept seconds or time values such as 00:02:30. Leave the range end empty to continue through the rest of the file. Keep the original format when it suits the destination, or choose MP3, WAV, M4A, AAC, OGG, Opus, or FLAC.
Changing output format re-encodes the clips and can affect processing time, file size, and quality. Splits may begin on the nearest decodable audio boundary, so allow a small margin when cutting speech or music precisely.
How to split audio online
- Choose an audio file and select fixed intervals, silence detection or a time range.
- Enter the timing or silence settings and select Preview segments. Adjust cuts, audition clips and edit names.
- Keep Original format or choose an output format, then export. Download each clip or the ZIP containing all clips.
Audio splitter FAQ
Which split mode should I choose?
Fixed intervals divide the recording by time. By silence suggests cuts at quiet gaps. Selected range exports one excerpt. Preview segments to edit the proposed cuts.
Why is the last audio clip shorter?
The last segment contains only the audio remaining after the final complete interval, so it can be shorter than the interval you selected.
Which time formats can I enter?
Enter plain seconds or a time such as 02:30 or 01:02:30. In Selected range mode, leaving End blank continues from Start to the end of the file.
Why did I receive a ZIP file?
One clip is downloaded as audio. Multiple clips are available individually and together in a ZIP. Edit the prefix or each clip name before export; duplicate names receive a suffix.
Why are silent gaps missed or too many cuts added?
Adjust the silence threshold and minimum gap duration. A higher threshold, such as -30 dB instead of -40 dB, classifies more sound as silence. Longer gaps and a longer minimum clip length produce fewer cuts. This detects quiet audio, not speakers or topics.
How is this different from removing silence?
Splitting puts boundaries inside silent gaps and preserves the recording. Silence removal shortens pauses and creates one continuous file. Original-format exports may cut near an encoded frame; choose WAV when precise boundaries matter.
How can I adjust and check a cut?
Prepare the segments, drag an orange marker in the waveform or edit its time in the list, then listen around the cut. Gray areas appear after silence detection. If waveform decoding is unavailable, time editing and splitting still work.
